PENHOLDER.

Specification of Letters Patent. Patented Mar. 16, 1920.

Application fiIed November 536, 1919. Serial No. 340,878.

which the following is a specification.

My inven ion relates to improvements in penholders and has for its object to provide a simple and ellicient means for releasing and ejecting the penpoint from the holder without the neccss L: of soiling the fingers.

A further object the invention lies in the manner which the venous parts cooperate so as to 'n'oducc an art cle that may be manufactured at a minimum cost, which is reliable in operation and capable of at taclnnent to pens oil. stz idard construction.

Other ob -es nd advantages of the invention will be apparent during the course of the following description.

in the acconing drawings forming a part of this eciiication and in which like numerals are employed to designate like parts throughout the same,

Figure 1, is a longitudinal it the penholdcr;

3, is an end view;

Fig. dais a transverse cross on line al'-1- of Fig. 1;

5, is a cross sectional view on line 55 of Fig. 1; and

Fig. 6, is a perspective view of the actuating lever.

In the drawings, wherein for the purpose of illustration 1 have shown a preferred embodiment of my invention, the numeral 5 designates the handle which is of any desired configuration and preferably constructed of wood. One end of the handle is reduced as at 6, having secured thereto the cylinder or tubular member 7 of metal or other suitable material being covered with rubber or cork material Sto providea grip. The end of the cylinder 7 is partially closed by the partition 9 which leaves a substan tially semi circular shaped opening 10 for the reception of the pen point 11. Disposed within the cylinder and secured thereto approximately midway its length is a piece of spring metal 12 which is riveted as at 13 to fixedly secure the strip against displacement. The forward portion of the strip is inclined upwardly as at 14 and termisectional view looking from sectional view mates with the curved spring finger 15. The opposite end of the strip 12 is bent upwardly at a right angle forming the vertically extending arm 16 which is apertured at its upper end, as at 17, for a purpose to be set forth later.

The lever 18 which forms the principal part of the attachment has its outer or enlarged end 19 concaved in cross section to conform with the interior shape of the cylinder. This end of the lever is disposed directly over the spring finger which normally holds the lever in contact with the penpoint 11 to prevent displacement thereof. The lever is bent approximately midway its length and extends downwardly in an inclined position as at 20, until in close proximity with the cylinder where it terminates in a button 21 which passes through an opening 22 in the cylinder. Adjacent the bend in the lever 18 a portion is out therefrom as at 23, being adapted to pass through the aperture 17 of the vertically extending arm 16 or" the spring 12. This arm forms a fulcrum for the lever as clearly shown in Fig. 1. Adjacent one end of theenlarged portion 19 of the lever is a transversely extending slot 2d, the purpose of'which is to receive the downwardly extending lug cut from the cylinder 7, so as to guide the movement of the lever 18 and also limit the insertion of the penpoint 11. The strip 12 not only forms a spring for retaining the enlarged portion of the lever 19 in contact with the penpoint, but also acts as a 111. crum for the lever when pressure is applied to the button 21 to release the enlarged portion 19 from engagement with the penpoint.

In use, the attachment is placed withn. the cylinder 7 after which the cylinder .is mounted upon the reduced end 6 of the holder 5 being secured thereto in any suit-- able manner. By applying pressure to the button 21 the lever 18 is rocked upon its lulcrum 23 which in turn will remove the enlarged portion 19 from out of contact with the cylinder so as to permit insertion of the penpoint 11. However, while this method of inserting the penpoint is most desirable it may be accomplished by forcing the penpoint between the enlarged portion and the cylinder as in the usual manner. As is well known after the penpoint has been used for a considerable time it becomes corroded so that it is rather diflicult to extract it from the holder, which difliculty is overcome by .niy improved attachment. That is, by applying pressure to the button 21, the enlarged portion willbe depressed downwardly so that the penpoint 11 will drop automatically from the holder without the necessity of soiling the fingers. It is obvious from the foregoing that the parts of my attachment cocperate in such a man ner asto produce an article of this character whichis very simple in construction and which may be easily'used in connectionwith penholders of the ordinary structure.

t is to be understood that the form of in invention herewith shown and described is to be taken as a preferred example of "the same, and that certain changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims. V

H'aving thus fully described my invention, I claim l. A penholder comprising a cylinder, a spring within the cylinder, and a lever tulcrumed to one end of the spring.

A penholder comprising a cylinder, :1 spring fixedly secured within the cylinder, and a lever tulcrunled to one end of the spring approximately intermediate its length, one'end of the lever being concaved transversely for contact with the inner periphery of the cylinder.

A penholder comprising a cylinder, a spring fixedly secured -within the cylinder approximately midway its length one 'end'oi' said spring being bent upwardly at a right'angle, and a lever tul crumed to'the upper end ofthe bent portion. 7

4c. A penholder comprising a cylinder, a spring secured withinthe cylinder, ther'orward end of which is inclined upwardly, while therear end is bent at a right angle, a lever l'ulcrumed to the upper end of the bent portion approxin'iately midway its length, said lever having one end concaved transversely for contact with the interior of the cylinder, and'its opposite end provided with a button which projects through an openin'g in the cylinder for actuating the "same. Y Y

5. A penholder comprising a cylinder, a spring fixedlysecured within the cylinder, one end oiwhic'h is inclined upwardly, while its opposite end is bent at a right angle, a lever fulcrumed to the upper end of the bent portion of the spring, said lever having one end curved transversely and held in contact with the cylinder bythe forward end of the spring, and its opposite end inclined clownwardly terminating in a button which projeets through an opening in the cylinder to permit actuating of the lever. V

G. A penholder comprising a cylinder, a spring fixedly secured within the cylinder,

a lever for gripping and retaining the penpoint in the holdensaid spring acting as a fulcrum for said lever, and also providing a spring arm which normally holds the lever in an operative position, and means for releasing the leve 7. A 'penholde'r comprising a cylinder, a spring fixedly secured within the cylinder, one end of said spring being bent upwardly at a ri htan 'le a lever fulcrumed to the forward end of the spring, a penpoint adapted to be inserted between the'curved portion of the lever and the-cylinder, and means depending from the cylinder ,passing through the lever for limiting the'i'nsertion of the penpoint and guiding the move ment of the lever.

In testimony whereof, I have'aiiixed my signature in the presence of two witnesses.
